File size

[TechnoTone]

I am trying to get the size of a file. I am using the Open method of the File class to get a FileStream object and using the Length property which is working fine when the file is accessible. However, most of the time the file will be open by another program. I've also tried to open the file using OpenRead and that still doesn't work.

 

How can I get the size of a file without actually opening it?

 

 

PS. The strange thing is that when I attempt to open a file that is in use by another pogram an exception doesn't occur. I just get nothing returned instead of a FileStream object. I would have thought an exception would be raised.

Use the FileInfo class;

 

Dim info As New FileInfo(path)
Dim fileSize As Long = info.Length

 

FileInfo info = new FileInfo(path);
long fileSize = info.Length;

I figured it was something simple - I just couldn't find it in the help.

 

Thanks.
